[Rd] R installation problem with shared libraries (PR#13900)

Submission from: (NULL) (216.113.168.130)


Configuration problem with the creation of shared libraries: Compilation only
succeeds if SHLIB_LDFLAGS="-shared" is added to the configure command line. This
is likely due to a wellknown gcc-4 feature, in that gcc requires -shared and not
just the linker flag -G to generate dynamically loaded libraries. However, even
if this variable is set at configuration time, it is not properly propagated to
the installed version, and one needs to patch the final installed version.

Specifics:

gcc -v 
Using built-in specs.
Target: x86_64-pc-solaris2.10
Configured with: ../../src/gcc-4.4.0/configure

When the newly built R is called by gmake during the build process, it throws an
error:

gmake[4]: Leaving directory `/usr/local/opt/build/R-2.9.1/src/library/base'
ld.so.1: R: fatal: relocation error: R_AMD64_PC32: file

As said, adding SHLIB_LDFLAGS="-shared" to the configure command fixes this
problem.

Even with this fix I also ran into a similar problem down the line when
compiling packages (specifically e1071), and it turns out that even if
specified, the flag is not fully propagated to the final installed version. I
found myself applying the following patch the final installed 2.9.1 version:

patch /usr/local/opt/x86_64-pc-solaris2.10/R-2.9.1/lib64/R/etc/Makeconf <<EOF
71c71
< SHLIB_CXXLDFLAGS = -G
---
> SHLIB_CXXLDFLAGS = -shared -G
EOF

Here is an example that triggers this error (just use any lazy-load package that
depends on another lazy-load package which had used g++ for the final linking
step).
